Abstract
A series of 7-substituted-3-cyclobutylamino-4H-1,2,4-benzothiadiazine-1,1-dioxide derivatives has been synthesized and evaluated as K(ATP) channel agonists using the inside-out excised patch clamp technique. The most active compounds were approximately 20-fold more potent than diazoxide in opening K(ATP) channels. A linear relationship exists between the potency of the compound and the sigma value of the 7-substituent with electron-withdrawing groups exhibiting higher activity. These compounds may be useful in modulating insulin release from pancreatic beta-cells and in diseases associated with hyperinsulinemia.
